Units are squared when dealing with area but not when dealing with perimeter true or false

understand that i don't know the answers

will someone answer his question

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

the answer is d

hope this
